A horizontal curve is being designed through rolling terrain for a six$-$lane

road with lanes that are $11-$ft wide. The central angle $()$ is known to be

$40$ degrees, the tangent distance $(T)$ is $525$ ft $,$ and the stationing of PI is

$3225+00.$ Under specified conditions and vehicle speed, the roadway

surface is determined to have a coefficient of side friction of $0\mathrm{.}11$ and the

curve's superelevation is $0\mathrm{.}05f\frac{t}{f}t.$ What are the stations of the PC and

PT$,$ and what is the safe vehicle speed?
